In his teens Moltmann was a keen student of chemistry, physics and maths, doing experiments in cellars with his friends and competing with them to learn more and more advanced theories. His education came to an abrupt halt when he was drafted into the German army at 16 and spent five years in uniform: about a year fighting and four years in British prisoner of war camps.

As a prisoner Moltmann, like many of his companions, suffered from boredom, horrific nightmares and deep depression. After his first winter in a Belgian camp the beauty of spring cherry blossom filled him with overwhelming joy. Eventually he was moved to a POW camp in Kilmarnock where he experienced warm hospitality and acceptance by his Scottish hosts, and began to feel human again. When a British army chaplain gave him a Bible Moltmann read it, first out of boredom and then with real interest. He realised that Jesus had also been through ‘the valley of the shadow of death’. Moltmann’s discovery of a God who loved him helped him to find hope again.

After just over a year of captivity Moltmann heard of a camp where the younger prisoners whose schooling had been interrupted by the war could study for university entrance exams. ‘Norton Camp’ had a well-stocked library and here the Moltmann read his first theology books, enjoying an almost monastic experience of intensive study and spiritual growth. After attending a post-war Student Christian Movement conference where he experienced reconciliation with young people who had fought on the other side, he decided to study theology.

In the second half of his lecture Moltmann spoke about the human dimensions of science: power, beauty, truth and wisdom. Unless ethical power develops as far as scientific power, science will remain dangerous.

Moltmann is the first person I have heard to actually flesh out what beauty in science looks like (though I expect others have written on this – answers on a postcard…) According to Moltmann, beauty in science can be experienced as symmetry, simplicity or unity. And beauty is seen most clearly when systems are moving from chaos to order, or vice versa. While beauty is not worth searching for in science for its own sake, Moltmann is convinced that beauty is a sign that you are nearer the truth, and that this sort of beauty is not subjective. Beauty may be useless from a utilitarian point of view, but it is meaningful in itself. I wonder how much an experience of the horrors of war informs this theologian’s love of beauty?
